Overall a fantastic game and considering it is now a budget title, a must own!
RR6 has several modes to play, including single player race, Online battle mode, and the World Xplorer mode, which is great fun. There are 4 class of cars plus a special class. There is an increase in speed with each class. The special class of car are unique cars from big boxy types to UFO Pac Man types. You start the game with only a handful of cars. You can download several from the XBOX market place, most if not all are free. As you progress in the World Xplorer mode, you will unlock cars and tracks to play in the single user mode. To unlock certain other items and achievements you will need to also play the Single Player mode, and win games in every class with no nitrous. Fortunately the Single Player mode keeps track of all these items.
RR6 also features replays you can save, as well as a spectator mode in the Online battles.
Graphically the game is fantastic, and the frame rate is always steady. The reflections and lighting are first class and really show case the 360's power. Considering this was a launch title, it holds up quite well. Namco did RR7 for PS3, and it features basically the same courses with a few new ones thrown in. Graphically RR6 is comparable to RR7 and I wish Namco would do a RR8 for 360 as I am sure they could eek out more power out of the 360 now.
There are a couple of down sides to the game, but they are minor annoyances and don't detract too much from the game experience. One annoyance is that you don't really crash in RR6. How can this be an annoyance? Instead of crashing, you just sort of bounce around off the walls until you either stop and straighten out or get hit and pushed back on course. If you don't drift correctly and do miss the turn you will see the bounce I am talking about. Another annoyance is that in the World mode some races are marked as no nitrous race, meaning you cannot use nitrous and are prevented from charging your nitrous gauge. The rub is that the computer players are not always prevented and you will see different levels of nitrous being used by the AI players. Sometimes they use it right when you are about to claim victory and rob you from it. Not cool at all. The final annoyance is the DJ that chatters during racing, wow does this guy not fit in a RR game. I don't know what they were thinking when they used this guy as the DJ! Like I said these annoyances are just that, and shouldn't keep you from enjoying the game.
Although it is not touched on in the manual too much, and not marked on the back of the case, there are several achievements to unlock. I found out by accident after I did a 360 spin in a race...
If you are a RR fan, or like arcade style racing with lots of unlockables, you simply must buy this game. Go on, get it now!
